Received the manual on CD today, It's in jpeg, pity it's not PDF but can live with it. Had a quick look at it and so far it looks good. Will have a more detailed look over the weekend and post my findings back here.

Hi bwigg and all,I've gone through the CD and it seems to have all the info one would need to carry out repairs, As I said before it's in JPEG format and it seems to be JPEG's of a photocopy of the manual. The text pages and block diagrams are very easy to read but the schematics are not of very good definition. but so far you can make out the ones I have looked at, but it's a pity they're not better for my ageing eyes. I'll report back when I get to sort out the problem on my R2600B, Mike ei2dj / g4gxn

Hi AllJust got a R2600C service monitor, everything is working 100% eccept the demodulator.Any ideas where to look and maybe a copy of the demodulator module PLS.....Any help will be apreciated !!Danie / ZS4JJ

When you say demodulator, does it look like it is receiving (something), but no volume, no squelch, no modulation display? A beep is heard on power-up so the speaker and audio amp are working.

IF so, there were two previous topics from 2012 and 2014 that may be of help - "2600 help needed" and "Squelch on MOTOROLA R 2600".Sorry, I can't remember how to quote the specific topics.

Basically, there is a problem on the Audio Board in slot 10. One of the more common problems a few users have seen is caused by leaking electrolytic capacitors on the Audio board. There are only two, but one or both can cause the problem. Essentially, one or more traces get damaged. One of them opens at a plate-thru, and the open is not apparent as the trace is in between PCB layers.

If this looks like what is happened, a simple repair may be possible. I use the word may because if the damage is confined to the audio board and not the backplane connector, then luck is on your side.

Pull the audio board and look near the edge connector. If traces near the two caps are discolored, then suspect corrosion.

Hi,does anyone have service manual for 2600D? Or at least diagram for display board? After power-on fan starts, beep from loudspeaker and short flash from ant and gen leds and lines in all colors on the screen. Backup battery and reference oscillator are OK. Any ideas?

Help, I have a R2670 which had a symptom of morning sickness, it would reboot when cold and then it was okay after warming up. Now it does not boot and no screen. It gives me 1 beep, pause, 3 beeps, pause and 1 beep. Power supply is good except for 40 volt is giving 34 volts. I have a hard copy of the R2600 maintenance manual but it says nothing about audible error codes.

Sounds like the CPU control board. I had the same issue and sent my r2660d to be refurbished for $1339.00
